Children in this group will continue to receive their treatment at the special education and rehabilitation center they attend, two days a week for 40 minutes.

GMFM is a standardized, valid and reliable scale that aims to determine capacity and change. It consists of five subsections: supine, prone and turning (A), sitting (B), crawling and kneeling (C), standing (D), walking, running and jumping (E). There are a total of 88 items in the subsections of GMFM. It is checked how much of each subsection the child has completed. Scoring is done according to a four-stage likert scale between 0-3. While the total score can be calculated, it is also possible to calculate each section on its own. Each section is converted into a percentage score within itself. Within the scope of our study, the evaluation will be made with the D and E sub-dimensions of GMFM-88 and percentage scores ranging from 0 to 100 will be calculated.

Normal selective voluntary motor control is the controlled performance of an isolated extremity movement without the occurrence of unwanted movements such as mirror-like movements and without the use of flexor and extensor patterns. The "Selective Control Assessment of the Lower Extremity- SCALE" test developed by Fowler et al. (21) in 2009 also evaluates the selectivity and quality of voluntary motor control of five regions (hip, knee, ankle, subtalar joint and toes) in the lower extremity. It has special definitions for each joint. According to the test scoring, the selectivity of the movement was defined as; 0=no movement

1. voluntary movement can be initiated but cannot be performed in a fully controlled, selective and high-quality manner
2. voluntary movement can be performed in a controlled, selective and high-quality manner.

The highest SCALE score for each extremity is 10, and the total lower extremity selective motor control score is 20 points.

It is an observational scale that rates the condition of the joints in the lower extremities according to the phases of walking. It was first used in the clinic by Koman et al. as the "Physician Rating Scale". OGS is an observational walking assessment that evaluates walking only in the sagittal plane. OGS, developed by Wren et al., evaluates the walking pattern with the items; knee position in the middle of the stance phase, first foot contact, foot contact in the middle of the stance phase, time of heel lift, rear foot in the middle of the stance phase, support area, use of assistive devices in walking. It measures from both the sagittal and frontal planes. The highest score for each extremity is 22. A high score indicates advanced walking skills. In this study, children will walk on a 6meter-long surface without devices, support or without support. Children of families who accept video recording will be videotaped during walking and the videos will be watched and OGS will be scored

The gross motor function classification system (GMFCS), developed by Palisano et al. for children with cerebral palsy, is based on child-initiated movements, with emphasis on sitting, moving, and mobility. It consists of five levels.

The general headings for each level are as follows.

Level 1: Walks without restrictions. Level 2: Walks with restrictions. Level 3: Walks using hand-held mobility devices. Level 4: Self-mobility is limited. May use powered mobility. Level 5: Transported in a hand-propelled wheelchair.

The Timed Up and Go Test is frequently used to assess functional mobility in adults. Williams et al. adapted the test for use in children, demonstrated the validity and reliability of the TUG in their study on healthy and disabled children, and reported that the TUG is a tool that can be used in children with special development and can measure changes in functional mobility over time. In a standard timed up and go test, the individual stands up from a chair, stands, walks 3 meters, and returns to the same chair, and the time between the command to stand and the individual sitting back in the chair is calculated.

It was developed by Franjoine et al. by modifying the adult "Berg Balance Scale". PBS has been shown to be valid and reliable in school-age children. It is a comprehensive and effective scale that evaluates balance in the following three dimensions: static balance, forward balance and functional movement transitions. The scale consists of 14 items including sitting balance, standing balance, sitting to standing/standing to sitting, transfers, taking steps, reaching forward with arm extended, reaching the ground, turning and placing foot on stool. Each item is rated from 0 to 4. 0 indicates inability to follow the instructions, while 4 indicates the ability to follow them without any difficulty. The lowest score that can be obtained from the scale is 0 and the highest score is 56, and as the score increases, it indicates advanced balance skills.

The Gillette Functional Gait Assessment Questionnaire is a walking scale applied to families by asking questions, and is a questionnaire that evaluates the walking ability of neurologically affected children who can and cannot walk, in public and outside the community, on a scale of 0-10. 0 indicates that the child cannot take a step and walk; 10 indicates that the child can walk and run on all surfaces without assistance and can go up and down stairs. In this study, the Gillette functional gait assessment questionnaire will be administered to families of children with CP via face-to-face interviews.

Weight transfer to the affected and unaffected lower extremities of children with unilateral CP is planned to be done with two scales of the same brand. The measurement will be made while the children stand with their feet shoulder-width apart, each foot on a different scale. The amount of weight transferred to their healthy and affected lower extremities will be written in kilograms (kg), and the difference between the weight transfer of both lower extremities will be recorded in kg.

It is a comprehensive clinical assessment tool that evaluates children's functional abilities and performance by asking the family. PEDI consists of three main sections under the subheadings of functional skills, caregiver assistance, and modifications. Each of these sections evaluates the areas of self-care, mobility, and social function. The functional skills section consists of 197 items and directly measures the child's functional abilities. In this section, the Self-Care subsection consists of 73 items, the Mobility subsection consists of 59 items, and the Social Functions subsection consists of 65 items. The child is given a score of 0; cannot do the items in this section and 1; can do them. At the end of each subsection, the scores of that section are added up and the Functional Skills Total Score is obtained by adding the scores of the subsections. The lowest score is 0 and the highest score is 197. As the score increases, the level of independence increases.

It is widely used to evaluate the effects of individualized, targeted physiotherapy and rehabilitation programs for children with CP. In order to measure the effect of the treatment, child-specific goals are determined together with the family, child and specialists. Goals are graded on five levels between -2 and 2. Goals should be specific, measurable, achievable, resource-sensitive and timely (SMART).

A value of "-2" indicates a value well below the desired goal, "-1" indicates a value below the desired goal, "0" indicates the desired goal, "1" indicates a success value above the desired goal, "2" indicates a success value well above the desired goal. It has a special calculation. For each target; the weighted score (Wi) is calculated according to the importance (i) and difficulty (d) scores (Wi=i X d).

IPFAM was developed by Stein and Reissman in 1980 to measure the level of impact on families of children with chronic, systemic, or progressive diseases. IPFAM questions the family's financial support, the disruption caused by the condition in social relationships, coping power, general impact, and total impact levels. It was translated into Turkish by Bek et al. It was planned that the mothers or fathers of the children to be evaluated within the scope of our study would fill out this scale. The person who fills out the scale will be the person who is more involved in the child's care among the parents.

The Communication Function Classification System classifies the communication skills of children with CP at the level of activity and participation. It was developed as an analogue of the GMFCS and Manual Ability Classification System (MACS). The GMFCS used in classifying CP in the literature has also been found to be related to other classification systems such as MACS.

Level 1: Effective giver and receiver with familiar and unfamiliar partners. The person can independently switch between giver and receiver roles with most people in most settings.

Level 2: Effective but slow-paced giver and receiver with familiar and/or unfamiliar partners.

Level 3: Effective giver and receiver with familiar partners. Level 4: Incompatible giver and/or receiver with familiar partners. The person's giver and receiver roles do not change continuously.

Level 5: Rarely effective giver and receiver even with familiar partners. The person is a limited giver and receiver.
